Not much change, ATP is neutral
The pH of water increase.
Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
The pH deccrease.
the water will get more acidic. the PH will decrease meaning the pH is acidic
In order to take a pH reading, water must be added to the solid. The water should be purified and have a known neutral pH.
decrease.

If it is common salt ( sodium chloride) the pH should not alter as they are both neutral substances at pH = 7.
As CO2 is added to water, the pH usually decreases.
The pH level goes down.
it raises in pH or becomes more basic
The pH increase significantly.
